The 20th Pumping Technology Research Conference will be held this year at the Osaka Institute of Technology, Joto Umeda Campus, Joto Hall, continuing from last year. The forwarding mortar used when employing concrete pumps has seen the development of alternative forwarding materials in recent years, which are now being used on-site. However, there has been a lack of systematic evaluation regarding their physical properties and the amount of waste generated when using these forwarding materials. Meanwhile, the "Forwarding Material Testing Method JIS Establishment Committee" has been established, and upon receiving a request for cooperation from this committee, we conducted pumping experiments in the 17th Field Experiment (2023) using various forwarding materials to qualitatively understand the appropriate usage methods for forwarding materials and the relationship between the properties of concrete and the amount that should be discarded. In this Pumping Technology Research Conference, we will report on this series of research findings.
